To all lw/"rom may concern Be it known that l., RAYMOND Gr. BULLooir, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful improvements in Compresser' for Filhig-Drawers, of which the following is a specification.

rlhe object of this invention is to provide a new and improved form of compressor for ling drawers.

make the compressor operable from without the drawer, so that the compressor may be operated whether the drawer is opened or closed.V

Another object of this invention is to construct a compressor so that it can adjust itself Vto the volume of sheets or papers that are within the drawer and exert a yielding pressure on4 them. u

Another object of this invention is to construct a compressor so that it may be used in connection with any of the compressors `heretofore constructed, this compressor being used at the front of the drawer, the

v'other compressors being used at the rear of A.the drawer.

These and other objects of my invention will be fully illustrated in the drawings, described in the speciiication and pointed out in the claims at the end thereof.

1n the accompanying drawings, Figure r1 is a front elevation of a case containing a drawer equipped with my improved compressor. Fig. 2 is a vertical section on the line 2*---2'X of Fig. l. Fig. 3 is a vertical section on the line SX-SX of Figs. 2 and 4i. Fig. 4; is a horizontal section on the line 4*-49 of Figs. 2 and 3. FigJJ is a vertical section vers 6 and 7 thereon, the inner ends of which project inside of the drawer. `Mounted. in

the inner ends ofthe levers 6 and 7 is the pin 8, the outer ends of which pin engaofe with slots 9 and 10 in the sliding meniber 11. This sliding member is channel shaped and the lower inner ends ofit are cut free from the front part of the channel and are bent in for a purpose that will presently appear.

The sides are finished with rounded projections 61, 61 which will make a snug sliding fit with the channel 12 with a minimum friction. Another object of this invention is to g The slidincn member -11 is mounted to move in the s iding channel 12 which channel is shown in perspective in Fi 7. This channel is cut away as indicate at 13 in Fig. 7 for the purpose of receiving the sliding member 11 which moves therein and has its bearing against the front wall 14 of the drawer. Fastened rigidly to the front wall.

of the drawer are the angles 15 and 16. One of these angles 15 is illustrated inside elevation in Fig. 5 and both of them are shown in front .elevation in Fig. 3 and in cross section in Fig. 4. Each of these angles is provided with slots 17 and 18. At the rear of these angles is placed the compressor 19. To this compressor is fastened four links 20, 21, 22 and 23. Each of these iinks extends forward and between the forward ends of the links 20 and 21 is supported the pin- 24 and between the forward ends of the links 22 and 23 is supported the pin 25. The pin 24E passes through the openings 26 and 27 at the `top ofthe sliding channel 12 and through the slots 18 in the angles land 16; The pin 25 passes through the openings 28 and 29 at the bottom or' the channel 12 and through the slots 17 of the angles 15 and 16. Pivotally fastened to the angle 15 are vthe links 30 and 31 and pivotally fastened to the angle 16 are the links 32 and 33. As

. the angles 15 and 16 are rigid with the front of the-drawer, the outer ends of the short The inner ends of the short links are pivotally connected to the middle of the long links 20, 22, 21 and 23. When the handle 5 is' moved. up or down, it is obvious that the sliding member 11 will move vdown or up to correspond therewith because of the engagement oi? the pin 8 with t e sliding member. It will also be observed trat the slots 9 and 10 are slightly turned up at the front so as to provide'positive engagement with the pin 8 when the lhandle 5 is inthe position shown links 30, 31, 32 and BBvwill remain fixed.

Tra'.

' in This holds the handle and the lcompressor locked in that position.

12. When the sliding member 11 is raised by placing the handle 5 inA the` position shown in IFig. 2, the springs 37 and 38 will 'be stretched, drawing with them the sliding channel 12 which in turn will raise the front ends ofthe links 20, 2f, 22 and 23 which will re-act with the short links 30, 32, 31 and 33 forming a toggle therewith which will be partiallyl straightened by this movement causing the compressor 19 to move rearwardly. y

`The compressor 19 is provided with a foot 40 `that engages with the channel 41 providedA in the bottom of the drawer by which it is held in position during its forward and back movement. It .will be -observed that the movement of the compressor 19 vis comparatively limited. The movement is just snliicient to aord the necessary compression so as lto hold the papers or photographic llilms orA sheets of other material that may be held inthe drawer, it being understood that the primary purpose of this invention is vto provide a drawer that will hold photographic films tightly pressed'together so as to .exclude the air from between them and thus minimize the danger therefrom on account of fire. The lilms or papers are compressed against the movable compressor 42 which slides along the channel 41 kand engages therewith and is held in vplace thereby in any well known manner.

The particular compressor illustrated herein, consists of an upright plate 43 having` a flange 44 on the bottom thereofl and having a'foot 45 fastened thereto similar to the foot'40 illustrated in Fig. 3' which footengages with the channel 41; Mounted on `brackets, 46 is t e pin 47 on which is Vpivotally mounted t e cam plate 48 which cam plate is pressed rearwardly at the tcp by l meansof the spring 49, the lower edge 50 of which cam plate engages with the bottom of the drawer for the purpose of holding the compressorv 42 firmly in position. The vplate 43 has a finger hole 51 struck up therein as is shown in Fig. 2 to facilitate the convenient operation of the compressor.

The compressor 19 can be operated to its compressing position by the handle 5 when the drawer is in any position provided the operator holds the drawer stationary but it can be automatically operated to compressing position when the drawer is pushed fully into the case that holds it. The operator can then force the compressor to its compressing and locked position by simply pushing down and back upon the handle 5i. When 4the drawer reaches the end of the case, its further movement will be blocked and the handle can then be operated to move and lock the compressor. .et quick pull up and vout on the handle 5 will release the compressor 19 fromlhe lock after which the drawer can be drawn out, all of which can be done by the operator using a single hand.

If a stop is provided in the path of the movement of the drawer, the drawer may be drawn'forward until it encounters such stop after which the handle may be drawn up for the purpose of releasing the compressor. In the foregoing ways, the operation of the compressor by the handle is automatic. It will also be understood that the drawer may be mounted on slides interposed between it and the casing such as are shown in the patent to Ripson and Sampson, Nos. 884,525 and 884,526.'
